DOOR LATCH.

Application filed February This invention has reference to a latch con-, struction especially designed for use in connection with doors of garages or similar buildings, the primary object of the invention being to provide a latch which may be locked against operation from a point exteriorly of the building, but may be operated from the interior of the building while locked.

An'important object of the invention is to provide a latch of this character which may be readily and easily secured to a door or closure and one which may be manufactured at a comparatively small cost.

WVith the foregoing and other objectsin View, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter de 20 scribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is an elevational View illustrating a portion of a closure or door supplied with a latch constructed in accordance with the invention.

Figure 2 is a sectional view taken on line 22 of Figure 1.

Figure 3 is an elevational view illustrating I the outer side of the door equipped with a latch of this type.

Figure 4 is a sectional view taken on line 44- of Figure 3.

Referring to the drawing in detail the reference character 5 designates a hinged door or closure which is supplied with a latch con structed in accordance with the present invention, the latch being secured to the inner surface of the door.

The latch is indicated by the reference character 6 and embodies an arm pivotally mounted on the shaft 7 formed at one end of the arm 8, the opposite end of the arm 8 being extended inwardly as at 9 to contact with the under surface of the latch 6 to raise the latch out of contact with its keeper.

As clearly shown by Figure 2 of the drawing, the free end of the shaft 7 is flattened as at 10 and is adapted to fit within the elongated opening formed at one end of the hasp 11 designed to receive the flattened portion so that movement of the hasp 10 8, 1928. Serial No. 252,859.

from a point exteriorly of the garage will result in a relative movement of the shaft and arm 8, to raise the latch 6.

An elongated opening 11 is formed in the hasp 11 and is adapted to receive the staple 12 through which a suitable pad lock is passed to lock the hasp against operation by unauthorized persons.

It is of course understood that the slot in the hasp 11 that receives the flattened end of the shaft 7, is sufiiciently large to permit of slight pivotal movement of the hasp 11, to allow it to be moved from a position out of contact with the staple 12 to the end that it may be swung laterally to operate the latch as described.

The reference character 13 indicates a keeper which is secured to a stationary portion of the building and is designed to be engaged by the shoulder 14 formed by the notch 15, so that the latch may be efliciently employed with either a door of the swinging type or sliding type with equally as good results.

A guide'indicated at 16 is secured to the door and acts to hold the latch member 6 against lateral movement at all times and i to relieve the shaft 7 on which the latch is loosely mounted of undue strain should pressure be exerted on the door, from the exterior thereof. 6

The operation of the latch is as follows:

Assuming that the latch has been locked and it is desired to open the door from a point Within the garage. It is only necessary to lift the latch 6v from its position within the keeper, whereupon the door may be opened.

It is obvious that when the door has been locked, it may only be, opened from a point exteriorly of the garage, by removing the pad lock and moving the hasp 10 to rotate the arm 8 lifting the latch member 6 by engagement of the portion 9 with the under surface of the latch.

It might be further stated that the outer lower edgeof the latch 6 is beveled so that it will ride over the keeper and position itself properly when used on a sliding closure.

I claim:

A latch for doors, including a latch arm, a keeper associated with the arm, a shaft extending through the door on which the arm is pivotally mounted, an arm extending an appreciable distance forwardly from the shaft and terminating in a right angled end disposed under the latch arm at a point remote from the shaft, said shaft having a flattened end portion a hasp fitted over the 5 flattened end portion to move with the shaft,

said hasp having an opening to accommodate a staple carried by the door to lock the has against movement, and said hasp providmg a handle to rotate the shaft and 0perate the latch arm to elevate the latch arm.

In testimony that I claim the foregoing as my own I have hereto affixed my signature.
